Embodiment
The present inventor develops one kind and realizes that receiver is poor using Wifi LANs first by in-depth study extensively
The method divided.Base station and movement station are placed under same LAN environment by this method, can realize movement station Differential positioning
Function, convenient and efficient without opening network service, easy to operate, portable, easily transplanting, differential delay are low.Base station and movement station connect
Connect same WIFI routes and carry out Differential positioning using NTRIP protocol realizations data interchange.Base station connects same WIFI with movement station
Route implementing movement station Differential positioning.And the same base station differential data sources progress difference of more mobile station apparatus acquisitions it can determine at the same time
Position, can also realize that multiple routers expand to broader region.
The method of the present invention is based on 2 points of designs：
1) WIFI is controlled
The WIFI patterns of base station and movement station can switch under AP and client patterns, i.e., be both used as hot spot confession
Other users connect, and are also used as client and connect other hot spots.In the present invention, hand-held terminal device is entered by bluetooth
Receiver webpage carries out parameter configuration to receiver.WIFI is operated in client patterns during operation of receiver, for connecting local
The WIFI of net, at this time, the router of LAN is without Internet enabled.After base station connects router with movement station, router
IP address can be distributed respectively to machine, IP address can be shown on handheld terminal.
2) communicate
Movement station, which carries out Differential positioning, to be needed to receive the differential data of base station, it is necessary to establishes certain data transfer chain.
This patent carries out data communication using NTRIP agreements, and NTRIPcaster is established in base station, arrange parameter, as shown in Figure 2.
Base station provides differential data source for movement station.
Movement station connects same router with base station, according to the base station IP shown in hand-held terminal device, establishes connection, such as
Shown in Fig. 3.
IP and port are set, clicks on and obtains differential data source list, and inputs user name, password and can be achieved to obtain base
Stand and differential data and realize difference.
The present invention is completed on this basis.
Term
As used herein, term " Differential positioning " refers to differentialpositioning, and one kind improves satellite navigation and determines
The technology of position precision.Satellite navigation reference receiver is set on known point, according to thus obtained satellite navigation observation or
